Press space or click to change direction. This isn't the full level, that will be coming soon. Also, the level isn't extreem difficulty, the full one is, this is probably just a easy level. (Before you guys tell me I misspelled 'extreem', I know it is actually spelt 'extreme', I just couldn't bother using grammar).
I permanently borrowed some version of the Tetris Theme and used that, the obstacles aren't synced to the music, just the speed changers.
